Configuration file not being correctly read on Windows

[justinclift]

Testing Dio 0.2.0 on win7, it's not reading the configuration file correctly.

When first run, it notices the missing configuration file and generates a template one for the user to modify:

C:\dev>dio-windows-386.exe
2019/04/13 23:10:44 No usable configuration file was found, so a default one has been
 generated in: C:\Users\user\.dio\config.toml
Please update it with your name, and the path to your DBHub.io user certificate file.

However, after updating the file with the path to the certificate and the correct username, the same message is returned, and the config file is overwritten.

It turned out the problem was TOML (our configuration format) doesn't like the backslashes in windows paths. eg C:\stuff.

Fixed by doubling the backslashes, from \ to \\, which TOML reads correctly.
